GET /wake?since=<stamp> is public (the apps hold no token) and rate limited (30 a minute per IP). It holds up to
45 s, re-reading the stamp every 2 s, and answers {stamp, at, added, changed, held_ms} the moment the stored stamp
differs from since, else the unchanged stamp at the deadline. POST /r/<token>/wake {stamp, added} (the relay's
auth, also x-relay-token or x-igneum-key on /wake) records a stamp; one row per stamp in relay_wake, created by the
first POST. maxDuration 60 s for api/wake.mjs in vercel.json. api/relay.mjs is untouched.
The handler lives in lib/wake.mjs with its dependencies injected; relay/test/wake.test.mjs drives it with a fake
database, a fake clock and a fake sleep (the hold, the change, the deadline, the rate limit, the hold cap, auth, a
database error). CI's site job runs it with the other relay tests.
